GUSTAF L. REENSTIERNA, OF WINCHESTER, MASSACHUSETTS.

CARBURETER.

SPECIFICATION forming part of Letters Patent No. 673.799, dated May '7,1901.

Application filed July 16,1900. Serial No. 23,717. (No model.)

To all ZUh/OWI/ it may concern.-

BeitknownthatLGUsTAF L REENSTIERNA, a citizen of the United States,residing at Winchester, in the county of Middlesex, State ofMassachusetts, have invented a certain new and useful Improvement inApparatus for Producing Gasolene Vapor, of which the following is aspecification, reference being had therein to the accompanying drawings.

My invention has relation to the apparatus which is employed for thepurpose of producing a combustible mixture of air and gasoleue or thelike liquid for use more especially as an explosive fuel ingasolene-engines.

The aims of the invention are to provide improved means for causingatmospheric air to make intimate contact with the supply of liquidgasolene and for insuring that the air shall become uniformly andcompletely charged with the gasolene; also, to provide a simple andconvenient closure device for the air-inlets, enabling the entire seriesthereof to be opened in unison to permit inflow of air when theapparatus is required to supply vapor and also enabling the entireseries of inlets to be closed in unison when the necessity for furthersupply of vapor ceases for the time being.

I have shown my invention in the accompanying drawings, in which- Figurel is a view in plan of a gasolene-receptacle having my in ventionapplied thereto. Fig. 2 is a view in vertical section on the planeindicated by the dotted line 2 2 in Fig. 1, looking in the directionindicated by the arrows at the ends of such line.

Having reference to the drawings, the receptacle for gasolene is shownat 1. It is represented as divided into two compartments by means ofavertical partition 2. (Indicated by a dotted line in Fig. 1.) In use thereceptacle is more or less completely filled with gasolene or the likefluid, the latter being intended to be represented at 3, Fig. 2. Theupper portion 4 of each compartment of the receptacle, above theliquid-level, constitutes a vapor-space which in the use of theapparatus becomes filled with a heavily'charged vapor produced bycausing atmospheric air from the exterior of the receptacle to come intointimate contact with the supply of liquid gasolene 3. From thevapor-space 4 a feed-pipe 5 leads to the gasolene-engine or other placeof consumption for the vapor.

The supply of liquid gasolene is introduced into the chambers of thereceptacle through openings which are closed by removable caps or thelike, as at 6 6, Fig. 1.

In the top 7 of the receptacle a circular hole is formed for eachchamber and at each of said holes the top is screw-threaded interiorly.(See Fig. 2.) A head 9 is provided in connection with each hole, thesaid head having a downwardly-extending exterior-lythreaded flange 10.The said flange is screwed into the hole until the rim 91 on the headbears against the upper surface of the top 7. Through the centralportion of the said head 9 is formed a number of holes, as at 101 101,650., Fig. 1. In the said holes are secured the upper ends of the seriesof small air-supplying tubes 11 11, Fig. 2. The lower ends of thesetubes project down below the liquidlevel within the receptacle, and whenthe suction of the piston of the engine draws out a portion of the vaporoccupying the vaporspace 4 fresh air is caused by atmospheric pressureto pass downward through the pipes 11 11 and rise in widely-distributedsmall bubbles through the liquid gasolene.

In connection with the head 9 I provide the disk-like cover 13, the saidcover being adapted to close the upper ends of all the tubes 11 11. InFig. 1 one cover is shown in position, the cover which belongs at therighthand side of the said figure being removed in order to show thearrangement of the series of tubes 11 11. The said cover 13 has acentral spindle 14:, extending down through a central hole in the head9, to guide the cover in its vertical movement. The gravity of the covermay be depended upon to keep it in place; but preferably I employ aspring 15 upon said spindle, compressed between the under side of thehead 9 and a washer 16 on the lower end of the spindle, the said washerbeing held in place by a split pin 17. For the purpose of holding thecover elevated during the use ofthe engine, so asto uncover the upperends of the tubes 11 11, &c., and allow air to enter freely into saidtubes, a pin 18 projects downwardly from the cover 13 and is adapted tobear upon the top of the head. When it is desired to close the saidupper ends of the series of tubes 11 11, &c., the cover is rotated bymeans of ones thumb and finger applied to the milled central boss 19 ofthe same, so as to carry the pin 18 around into position to enter a hole20, that is formed in the central part of the head 9. This cover enablesthe entire series of airtubes 11 11 for each chamber of the receptacleto be closed or unclosed in unison. One or more diaphragms ofwire-netting, as at 21, Fig. 2, may be employed in practice Within eachchamber of' the receptacle in order to strip from the vapor any excessof gasolene in liquid form carried up by the ascending vapor. Theair-tubes 11 11 admit the entering air in small streams at a number ofplaces, so that the air is admitted in only a small quantity at a givenplace, and thus is completely brought into contact with the liquidgasolene, the loading or charging of the air with gasolene to form therequired vapor being thereby more effectually accomplished than would bethe case if the air Were allowed to flow in through one or more largepassage-ways. This mode of producing the vapor obviates tendency tooversaturation of the air with liquid, only so much gasolene being takenup by the air as the latter can carry.

It is contemplated that the receptacle to which myinvention is appliedshall be employed in connection with a moving vehicle of theself-propelled class. For the purpose of preventing excessive agitationof the liquid contents of the receptacle, as Well as bracing the innerends of theair-tubes ll 11, so as to stifien and steady the same, Iapply a plate 22, Fig. 2, to the said air-tubes adjacent the usual toplevel ofthe liquid gasolene.

I claim as my invention 1. The improved vapor-producing apparatuscomprising the receptacle for liquid gasolene, or the like, having thevapor-space and a feed-pipe for vapor leading from said vapor-space, theseries of small air-supply tubes conducting air in small streams intothe liquid gasolene, and the gravitating or spring-actuated coverapplied to the outer ends of the series of tubes and serving to cover oruncover the entire series at onetime, substantially as described.

2. The improved vapor-producing apparatus comprising the receptacle forliquid gasolene, or the like, having the vapor-space,

and a feed-pipe for vapor leading from said vapor-space, a series ofsmall air-tubes conducting air in small streams into the liquidgasolene, and the gravitating or spring-actuated cover applied to theouter ends of the series of tubes and serving to cover or uncover theentire series at one time, the said cover having the pin 18 entering ina given position of the cover a hole provided for its reception, thesaid pin acting in another position of the cover to hold the latterelevated, substantially as described.

3. The improved vapor-producing apparatus comprising the receptacle forliquid gasolene having the vapor-space and a feedpipe for vapor leadingfrom said vapor-space, the series of small air-supply tubes conductingair in small streams into the liquid gasolene, the cover applied to theouter ends of the series of tubes, and the plate 22 applied to the innerportions of the said air-tubes adjacent the usual top level of theliquid contents of the receptacle, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
